       The  munge  program  creates  an  MUNGE  credential  containing  the  UID and GID of the calling process.
       Additional payload data can be encapsulated in as well.  The returned credential can be passed to another
       process which can validate its contents (e.g., via the unmunge program).  This allows  an  unrelated  and
       potentially remote process to ascertain the identity of the calling process.

       By default, payload input is read from stdin and the credential is written to stdout.

       The munge program returns a zero exit code when the credential is successfully created and returned.   On
       error, it prints an error message to stderr and returns a non-zero exit code.

-h,--help
              Display a summary of the command-line options.

       -L,--license
              Display license information.

       -V,--version
              Display version information.

       -n,--no-input
              Discard all input for the payload.

       -s,--stringstring
              Input payload from the specified string.

       -i,--inputpath
              Input payload from the specified file.

       -o,--outputpath
              Output the credential to the specified file.

       -c,--cipherstring
              Specify the cipher type, either by name or number.

       -C,--list-ciphers
              Display a list of supported cipher types.

       -m,--macstring
              Specify the MAC type, either by name or number.

       -M,--list-macs
              Display a list of supported MAC types.

       -z,--zipstring
              Specify the compression type, either by name or number.

       -Z,--list-zips
              Display a list of supported compression types.

       -u,--restrict-uiduid
              Specify  the  user name or UID allowed to decode the credential.  This will be matched against the
              effective user ID of the process requesting the credential decode.

       -U,--uiduid
              Specify the user name or UID under which to request the credential.  This requires root privileges
              or the CAP_SETUID capability.

       -g,--restrict-gidgid
              Specify the group name or GID allowed to decode the credential.  This will be matched against  the
              effective  group ID of the process requesting the credential decode, as well as each supplementary
              group of which the effective user ID of that process is a member.

       -G,--gidgid
              Specify the group name or  GID  under  which  to  request  the  credential.   This  requires  root
              privileges or the CAP_SETGID capability.

       -t,--ttlseconds
              Specify the time-to-live (in seconds).  This controls how long the credential is valid once it has
              been  encoded.   A  value of 0 selects the default TTL.  A value of -1 selects the maximum allowed
              TTL.  Note that munged can impose a maximum allowable TTL for all credentials which may be smaller
              than this value.

       -S,--socketpath
              Specify the local socket for connecting with munged.
